I get it all the time with our rottie.
People say that their mates' rottie would be an ideal stud for us, and think of the money we'd make.
I let them ramble on for a bit then tell them to 'F' off,

as I wouldn't put out to stud with any dog that they mention..i.e...Excellent guard dog...would rip this dog or that dog to shreads..is really bulky if you know what i mean..ie steroids !!!
Sadly people still do this to their dogs !! And its mostly the neds who thinks its really cool to have a very large muscluar dog !!! When they are only about 9-10stone themselves !

I guess some people might be genuine, but others just see
